Energy Solution by Hybrid Energy System at Bhasan Char

Abstract

Due to its environmental friendliness and availability of resources, renewable energy sources are being adopted by numerous nations around the world for electrification. In this study, a hybrid islanded microgrid system is proposed for the electrification of Bhansan Char, the location of the Rohingyas' most recent relocation. The hydrogen fuel cell (HFC), wind, solar power, and biogas generation are all included in the model design. The system maximizes the conversion of renewable energy into electricity. Experimental testing has proven that the modeled hybrid energy system efficiently produces electric energy for a remote site under various environmental conditions, such as for a cloudy sky. A feasibility analysis for the electrification of the island is conducted using the preliminary load structure of Bhansan Char. The technical study is carried out by building the project in Matlab for the best case from HOMER, while the economic analysis is carried out using the HOMER program. It is intended to supply the 26 MWh daily electricity requirement and 4.2 MW peak load. Based on the system's Net Present Cost (NPC) and Cost of Electricity (COE), the optimum system configurations were selected. The results demonstrate that a hybrid solar/wind/fuel cell/biomass system is more effective in an isolated place like Bhansan Char, where connecting to the national grid is a significant barrier, in terms of power consumption and efficiency. The project is extremely efficient and effective over the long term despite its high starting cost.
